Broad Run High School

Broad Run High School is a public secondary school in Ashburn, an unincorporated area in Loudoun County, Virginia, United States. Broad Run is part of the Loudoun County Public Schools system. It was ranked as the #3 Best Public High School in Loudoun County and the #18 Best Public High School in Virginia by Niche in 2018.

Of the county's fifteen public high schools, Broad Run has experienced the most change in both its physical and demographic environments during its nearly five decades of existence. Originally a rural school serving all of eastern Loudoun County, the explosive growth of the county's population beginning in the mid-1990s has resulted in systematic reduction of Broad Run's attendance area as it spun off eight of the district's high schools from within its original boundaries.
